The bar graph below shows the number of men and women in different classes. A bar graph showing the number of men and women in two different classes, Chemistry and Law.
A side-by-side bar graph has a horizontal axis labeled Classes with groups Chemistry and Law and a vertical axis labeled Students from 0 to 14 in increments of 2. There are two vertical bars over each horizontal axis label, with the bar on the left representing men and the bar on the right representing women. The heights of the bars are as follows, with the horizontal axis label listed first and the bar heights listed second from left to right: Chemistry, 14 and 11; and Law, 12 and 13.

How many total students are in the Chemistry class? Do not include the units in your answer.

Overproduction of uric acid in the body can be an indication of cell breakdown. this may be an advance indication of illness such as gout, leukemia, or lymphoma.† over a period of months, an adult male patient has taken nine blood tests for uric acid. the mean concentration was x = 5.35 mg/dl. the distribution of uric acid in healthy adult males can be assumed to be normal, with σ = 1.87 mg/dl. (a) find a 95% confidence interval for the population mean concentration of uric acid in this patient's blood. what is the margin of error? (round your answers to two decimal places.) lower limit upper limit margin of error (b) what conditions are necessary for your calculations? (select all that apply.) σ is unknown n is large σ is known normal distribution of uric acid uniform distribution of uric acid (c) interpret your results in the context of this problem. there is not enough information to make an interpretation. the probability that this interval contains the true average uric acid level for this patient is 0.05. the probability that this interval contains the true average uric acid level for this patient is 0.95. there is a 95% chance that the confidence interval is one of the intervals containing the population average uric acid level for this patient. there is a 5% chance that the confidence interval is one of the intervals containing the population average uric acid level for this patient. (d) find the sample size necessary for a 95% confidence level with maximal margin of error e = 1.10 for the mean concentration of uric acid in this patient's blood. (round your answer up to the nearest whole number.) blood tests
